In terms of overall gaming performance, the Intel Core i3-9350KF 4-Core 4.0GHz is massively better than the Intel Core i7-870S Quad 2.67GHz when it comes to running the latest games. This also means it will be less likely to bottleneck more powerful GPUs, allowing them to achieve more of their gaming performance potential.

The Core i3-9350KF 4-Core was released over three years more recently than the Core i7-870S Quad, and so the Core i3-9350KF 4-Core is likely to have far better levels of support, and will be much more optimized and ultimately superior to the Core i7-870S Quad when running the latest games.

Both CPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings (assuming they are accompanied by equivalently powerful GPUs).

The Core i3-9350KF 4-Core and the Core i7-870S Quad both have 4 cores, which is not likely to be a limiting factor for gaming.

The Core i7-870S Quad has 4 more threads than the Core i3-9350KF 4-Core. The Core i3-9350KF 4-Core has one thread per physical core, whereas the Core i7-870S Quad uses hyperthreading and has 2 logical threads per physical core.

Multiple threads are useful for improving the performance of multi-threaded applications. Additional cores and their accompanying thread will always be beneficial for multi-threaded applications. Hyperthreading will be beneficial for applications optimized for it, but it may slow others down. For games, the number of threads is largely irrelevant, as long as you have at least 2 cores (preferably 4), and hyperthreading can sometimes even hit performance.

More important for gaming than the number of cores and threads is the clock rate. Problematically, unless the two CPUs are from the same family, this can only serve as a general guide and nothing like an exact comparison, because the clock cycles per instruction (CPI) will vary so much.

The Core i3-9350KF 4-Core and Core i7-870S Quad are not from the same family of CPUs, so their clock speeds are by no means directly comparable. Bear in mind, then, that while the Core i3-9350KF 4-Core has a 1.34 GHz faster frequency, this is not always an indicator that it will be superior in performance, despite frequency being crucial when trying to avoid GPU bottlenecking. In this case, however, the difference is probably a good indicator that the is superior.

Aside from the clock rate, the next-most important CPU features for PC game performance are L2 and L3 cache size. Faster than RAM, the more cache available, the more data that can be stored for lightning-fast retrieval. L1 Cache is not usually an issue anymore for gaming, with most high-end CPUs eking out about the same L1 performance, and L2 is more important than L3 - but L3 is still important if you want to reach the highest levels of performance. Bear in mind that although it is better to have a larger cache, the larger it is, the higher the latency, so a balance has to be struck.

The maximum Thermal Design Power is the power in Watts that the CPU will consume in the worst case scenario. The lithography is the semiconductor manufacturing technology being used to create the CPU - the smaller this is, the more transistors that can be fit into the CPU, and the closer the connections. For both the lithography and the TDP, it is the lower the better, because a lower number means a lower amount of power is necessary to run the CPU, and consequently a lower amount of heat is produced.

The Core i7-870S Quad has a 9 Watt lower Maximum TDP than the Core i3-9350KF 4-Core. However, the Core i3-9350KF 4-Core was created with a 31 nm smaller manufacturing technology. Overall, by taking both into account, the Core i3-9350KF 4-Core is likely the CPU with the lower heat production and power requirements, by quite a wide margin.

CPU Mini Review

Mini ReviewThe Intel Core i3-9350KF 4-Core 4.0GHz is a mid to low-end CPU based on Intel's 9th Gen 14nm, Coffee Lake refresh microarchitecture. It offers 4 physical cores (4 logical), initially clocked at 4.0GHz, which may go up to 4.6GHz using Turbo Boost. It has an unlocked multiplier and can therefore be overclocked using traditional methods. It has 8MB of SmartCache. Intel SmartCache refers to the architecture that allows all cores to dynamically share access to the last level cache. Level 3 cache is a static memory bank of a processor and it is used to feed it instructions. This processor also supports DDR4 based RAMs with maximum memory support of 64GB. It has a maximum Thermal Power Design of 91W. It is on par with competitor processors. Among its many advanced features are Intel Optane Memory support, Intel Turbo Boost 2.0 and Virtualization technology. It Intel Core i3-9350KF features no onboard integrated graphics. This CPU is likely to offer decent computational performance and will not be a bottleneck in all but the most CPU-intensive AAA games in 2019.Core i7-870S Quad 2.66GHz is a power efficient CPU based on the 45nm, Nehalem architecture.

It offers 4 Physical Cores (8 Logical), initially clocked at 2.66GHz, which may go up to 3.6GHz and 8MB of L3 Cache.
Among its many features, HyperThreading, Turbo Boost and Virtualization are activated.

The processor DOES NOT integrated any graphics and has a rated board TDP of 82W.

It is a powerful Quad Core whose performance is good. It's thus capable of running most applications smoothly without any problem.
